Abstract
A control method is introduced to operate an ACF power converter under a non-complimentary mode. A high-side switch is turned ON at least twice within a switching cycle of a low-side switch, to provide at least two high-side ON times. One of the high-side ON times follows the end of demagnetization time of a transformer in the ACF power converter, and the other follows the end of the blanking time that controls the maximum switching frequency of the low-side switch.
